Question

c++构造函数，vs2010报错说有返回值，求给看看

Box::Box(double aLength,double aWidth,double aHeight){
length=aLength>0.0? aLength:1.0;
width =aWidth >0.0? aWidth :1.0;
height=aHeight>0.0? aHeight:1.0;
}
class Box{
public:
Box(double aLength=1.0,double aWidth=1.0,double aHeight=1.0);
double volume() const;
double getLength() const;
double getWidth() const;
double getHeight() const;
int compareVolume(const Box& otherBox) const;
private:
double length;
double width;
double height;
}

Answer 1

类中构造函数中不是已经初始化了吗

Answer 2

CPP里的代码呢?

Answer 3

类后面加个；号
